Problems solved by technology

[0003] Among field emission display devices with a three-electrode structure, most displays currently adopt a structural mode in which the gate structure is located above the carbon nanotube cathode structure. The manufacturing process is simple and the gate control function is significant, but the gate current is relatively large. , the gate voltage remains high, which is the disadvantage of
